Performance analysis of FPGA controlled four-leg DSTATCOM for multifarious load compensation in electric distribution system

A field programmable gate array (FPGA) controlled four-leg distribution static compensator (FL-DSTATCOM) has been implemented to achieve harmonic alleviation, supply current balancing, compensation of reactive power and current flow in the neutral conductor of a 4-wire 3-phase electric distribution...
